Given numbers are 780, 255, 149, 703

The list of prime factors of all numbers are

Prime factors of 780 are 2 x 2 x 3 x 5 x 13

Prime factors of 255 are 3 x 5 x 17

Prime factors of 149 are 149

Prime factors of 703 are 19 x 37

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 780, 255, 149, 703

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(780, 255) = 13260

GCD(780, 255) = ( 780 x 255 ) / 13260

= 780 / 255

= 780

Step2:

LCM(15, 149) = 2235

GCD(15, 149) = ( 15 x 149 ) / 2235

= 15 / 149

= 15

Step3:

LCM(1, 703) = 703

GCD(1, 703) = ( 1 x 703 ) / 703

= 1 / 703

= 1

So, Greatest Common Divisor of 780, 255, 149, 703 is 1
